DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0021] A flat rack straight cable pulley, such as Figure 1 and Figure 3As shown, it includes a flat frame 1 and a pulley body 2, a left support plate 3 and a right support plate 4 are fixed on the upper surface of the flat frame 1, a round shaft 5 is fixed between the left support plate 3 and the right support plate 4, a round hole 16 is opened on the pulley body 2, and ball bearings 17 are fixed to the left and right outer ports in the round hole 16, and the inner rings of the two ball bearings 17 are jointly installed with the round shaft 5, the pulley body 2 is rotatably installed on the outer wall of the round shaft 5 through the ball bearings 17, the ball bearings 17 have good rigidity and a small friction coefficient, can effectively reduce friction and energy loss during rotation, and improve the efficiency and service life of the cable pulley, the cable is placed on the pulley body 2, and when the cable moves, the pulley body 2 rotates, and the direction of the cable is guided by the rotation, thereby improving the smoothness and stability of the routing.

[0022] like Figure 2 As shown, the outer surface of the pulley body 2 is a smooth surface to prevent the outer wall of the cable from being damaged, and also to reduce the friction between the cable and the outer surface of the pulley body 2. The pulley body 2 is made of polytetrafluoroethylene, which has many unique physical properties. The low friction coefficient can reduce the mechanical energy lost during the cable routing process, and it also has good wear resistance, which makes the pulley body 2 have a long service life. A pair of fixing ears 18 are installed on the outer surfaces of the left and right sides of the flat frame 1, and mounting holes 19 are opened on the fixing ears 18. Bolts are passed through the mounting holes 19 to fix the flat frame 1 to the wall or the ground to fix the position of the cable pulley.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a first slide groove 6 is provided on the left surface of the left support plate 3, and a second slide groove 7 is provided on the right surface of the right support plate 4. Two vertical rods of a gate-shaped cable tie rack 8 are slidably installed inside the first slide groove 6 and the second slide groove 7 respectively. The gate-shaped cable tie rack 8 can move up and down in the first slide groove 6 and the second slide groove 7, and the left and right outer walls of the gate-shaped cable tie rack 8 are threadedly connected with fastening screws 9. A plurality of first threaded holes 11 are evenly spaced in the first slide groove 6, and a plurality of second threaded holes 12 are evenly spaced in the second slide groove 7. The outer ends of the fastening screws 9 are also connected with plum blossom handles 10. The fastening screws 9 are matched with the first threaded holes 11 and the second slide groove 7. The number of the first threaded holes 11 and the second threaded holes 12 is the same, and the first threaded holes 11 and the second threaded holes 12 are horizontally arranged. The two screws 10 are respectively screwed together and the screws 11 are screwed together to fix the position of the door frame 8.

[0024] When the embodiment 1 is working, the user line fixes the position of the flat frame 1 through the mounting hole 19 on the fixing ear 18. When the cable is routed, the pulley body 2 rotates to guide the direction of the cable by rotation, thereby improving the smoothness and stability of the routing. A first slide groove 6 is provided on the left surface of the left support plate 3 on the upper surface of the flat frame 1, and a second slide groove 7 is provided on the right surface of the right support plate 4. Two vertical rods of a gate-shaped cable tie rack 8 are slidably installed inside the first slide groove 6 and the second slide groove 7, respectively. The outer walls of the left and right sides of the gate-shaped cable tie rack 8 are both threadedly connected with fastening screws 9, and the outer ends of the fastening screws 9 are also connected with plum blossom handles 10. A plurality of first threaded holes 11 are evenly spaced in the first slide groove 6, and a plurality of second threaded holes 11 are evenly spaced in the second slide groove 7.

When the fastening screws 9 on the left and right sides are not threadedly connected with the first threaded hole 11 and the second threaded hole 12 respectively, the fastening screws 9 are moved up and down, thereby driving the door-shaped cable tie frame 8 to move up and down in the first slide groove 6 and the second slide groove 7. The door-shaped cable tie frame 8 constrains the activity space of the cable to prevent the cable from being dislocated from the pulley due to position displacement, thereby avoiding the slowdown of the project progress caused by the cable disengagement, and wasting time and manpower and material resources. At the same time, the height of the door-shaped cable tie frame 8 can be flexibly changed, thereby flexibly changing the size of the cable activity space, and it can also be suitable for cables of different diameters. Example 2

[0025] Embodiment 2 is based on embodiment 1, as Figure 4 As shown, bearing seats 13 are fixed to the inner walls of the left and right sides of the gate-shaped cable rack 8, and a roller 14 is installed between the left and right bearing seats 13 for common rotation. A roller 15 is sleeved and fixed on the outer wall of the roller 14. When the cable is routed and friction occurs between the cable and the outer wall of the roller 15, the roller 14 rotates on the left and right bearing seats 13, and the roller 15 also rotates accordingly to guide the cable routing.

[0026] When embodiment 2 is working, when friction occurs between the cable and the roller 15, the roller 15 reduces the friction between the cable and the roller 15 by rotating. At the same time, the establishment of the roller 15 can prevent the cable from colliding with the door-shaped cable tie rack 8. The roller 15 also provides a smooth surface to avoid damage to the outer wall of the cable. The roller 15 also improves work efficiency by making the cable routing smoother.
